Answer 2

Explanation:

Frequency of string A, fA = 324 Hz

Frequency of string B = fB

Beat’s frequency, n = 6 Hz

Beat’s Frequency is given as:

Frequency decreases with a decrease in the tension in a string. This is because frequency is directly proportional to the square root of tension. It is given as:

v ∝ √T

Hence, the beat frequency cannot be 330 Hz

∴ fB = 318 Hz.
